Che's 'betrayer' tells his side of the story

Ciro Bustos was 26 and at his in-laws' house for a barbecue one spring Sunday in 1958 when he first heard the voice. It belonged to a fellow Argentinian, a doctor four years his senior who was fighting alongside Fidel Castro in the mountains of south-eastern Cuba.

As he listened to the radio, the young artist was struck by the contrast between the grandiloquence of the Cuban and the quiet, almost apologetic tones of the Argentinian."The way Che spoke, the way he answered questions, was totally different from Castro," says Ciro, whose recollection of the broadcast has not been blunted by the intervening half-century.
